I was trying to setup my raspberry pi in crontab to reboot every time at midnight, it didn't work, So I set it to run the command every minute, didn't work, so I put sudo in front of reboot, now I have a raspberry pi rebooting every minute, and I can't stop it. facepalm I know...
Does anyone have any idea how to stop it?
As you have done all the progress on the crontab, I suggest resetting it to the default configuration.
Try the command below to reset it (the -r flag removes current crontab configuration.):
crontab -r
You can also use crontab -e and manually delete everything inside. Another option is -l to get a list of crontab configuration as an output.
In addition, You can use the -u flag to change someone else's configuration followed by the corresponding username.
If the vi editor bothers you, you can open/edit the crontab by adding export VISUAL=nano; before the crontab command with any flag you want like:
export VISUAL=nano; crontab -e
crontab -r worked like a charm, I only have 5-10 seconds to clear it it again before it reboots again. doing it manually would take too long. THANK YOU SO MUCH!!!!
